Chicago-Latrobe 54064 11/32 in Cobalt Drill Bit
This Chicago-Latrobe 54064 drill bit is a jobber-length cutting tool made from cobalt steel with a titanium nitride coating. It suits metalworkers and maintenance technicians who need a durable bit for drilling hard materials such as stainless steel or cast iron. The 11/32 inch size covers a common clearance-hole requirement in automotive and fabrication shops.
135° Split-Point Geometry Reduces Walking
The 135 degree split point is designed to start on contact without a centre punch, helping the bit stay on target during hand-held or drill-press use. Cobalt construction resists heat buildup, but excessive feed pressure or insufficient lubrication can still chip the cutting edges. The TiN coating lowers friction, yet it will wear away if the bit runs dry at high speed.
Sustained Drilling in Tough Alloys
Under continuous load the cobalt substrate retains hardness better than standard high-speed steel, allowing longer cuts before re-sharpening. Heat accumulates in deep holes because the bit has no coolant-through channels, so periodic withdrawal is necessary to clear chips and let the tip cool. The coating delays galling, but material adhesion increases once the surface layer is gone.

Questions about this item
How do I confirm the 135° split point is cutting cleanly after setup?
A properly working bit will start on contact without wandering and produce short, curled chips in steel; the TiN coating should stay gold with no blue discolouration at the tip.
What comes in the box and what must I supply?
The box contains the single 11/32 in cobalt jobber-length drill bit; you must supply a compatible drill chuck, cutting fluid and the workpiece.
Which version of the 54064 should I choose for general steel drilling?
The 54064 is offered in one specification — 11/32 in diameter, 135° split point, cobalt with TiN coating — so that single version covers general steel drilling.
